Wednesday night one of my 580,000 tweets blew up. I didn’t live up to my own standards, and I didn’t meet USA TODAY’s standards. For that I apologize, to USA TODAY readers and to my followers on social media.

I was following the riots in Charlotte, against a background of reports of violence. Joe Bruno of WSOC9 interviewed a driver whose truck had been stopped by a mob. Trapped in her cab, she “feared for her life” as her cargo was looted. Then I retweeted a report of mobs “stopping traffic and surrounding vehicles” with the comment, “Run them down.”

Those words can easily be taken to advocate drivers going out of their way to run down protesters. I meant no such thing, and I’m sorry it seemed I did. What I meant is that drivers who feel their lives are in danger from a violent mob should not stop their vehicles. I remember Reginald Denny, a truck driver who was beaten nearly to death by a mob during the 1992 Los Angeles riots. My tweet should have said, “Keep driving,” or “Don’t stop.”
